ACETYLENE-GAS APPARATUS.

Application filed October 29, 1915.

To all whom t may concern:

Be it known that I, CHARLES P. VERNIER, a citizen of the United States, residing at ledar Rapids, in the county of Linn and State of Iowa, have invented new and useful Improvements in Acetylene-Gas Apparatus, of which the following is a speciiication.

rlhis invention relates to improvements in the construction of acetylene gas apparatus, and the primary object of the invention is to produce an apparatus of this character which shall be simple in construction, comparatively cheap to manufacture and which shall be thoroughly efficient in operation.

Another object of the invention is to provide the carbid tank of the apparatus with two valves, one arranged in advance of the other and both closed by a counterweight, each of the valves having their stems arranged in suitable guides and both of the valves being unseated by the movement of the bell, one in advance of the other, while the counterweights reseat `the valves in a like manner; that is, one of the valves is seated slightly in advance of the otherl valve Other objects and advantages will appear as the nature of the invention is more fully understood, reference being had to the accompanying drawings, in which:

Figure 1 is acentral vertical longitudinal sectional view through the improvement, Fig. 2 is a similar sectional view approximately on the line jz/-fy of Fig. 1, and Fig. 3 is a perspective view of the carbid receiving pan.

Referring now to the drawings in detail, the numeral 1 designates the casing of the apparatus, the same being provided, adjacent its lower and closed end, with what I will term an inner lining 2, the same being provided with a plurality of openings 3 so that the water which is received in the casing may flow between the same and the said inner lining. The inner lining 2, at its upper end, has resting thereon or secured thereto a carbid tank 4, the same having a lower funnel-shaped portion 5 that extends within the inner lining 2, and the open mouth of the funnel-shaped portion 5 is surrounded by a discharge spout 6, the said spout 6 being of a greater cross sectional diameter than the area of the outlet 7 of the funnelshaped portion 5 of the carbid tank 4. The upper and closed end of the tank 4 is provided with a iiangeol inlet opening 8 which is normally closed by a cap 9, and the said tank 4 is` centrally provided with a verti- Speccation of Letters Patent.

cally arranged sleeve 10 which communicates with the closed top of the tank and which terminates some distance above the outlet 7 thereof. The sleeve 10 is provided with a hollow cone-shaped guide 11 which is arranged adjacent its lower end and which is disposed a suitable distance away from the lower inclined walls of the tank 4, and the member 11 is adapted to guide the carbid which may collect around the sleeve 10 to the space between the lower edge of the said member 11 and the inclined walls of the funnel-shaped portion 5 of the tank, so that the same may gravitate thereon through the outlet opening 7. rlfhe outlet opening 7 provides a seat for a valve 12, the same having its upper face round and the numeral 13 designates the hollow stem for the valve 12 which passes through the sleeve 10 above the closed top of the tank 4. The upper end of the sleeve is provided with a collar 14 having a downwardly curved finger 15 which engages an oppositely curved finger or end 16 formed upon a lever arm 17. This lever arm 17 is centrally and pivotally connected with a pivotally mounted support 18 provided upon the top of the tank 4, and the opposite or free end of the said lever arm has pivotally attached thereto a rod, or if necessary, a iieXible element, indicated by the numeral 19, the said member 19 passing through a sleeve or pipe member 20 arranged between the upper and lower walls of the tank 4. The end of the member 19 has secured thereto a weight 21 which normally tilts the lever arm 17 to move the stem 13 of the valve 12 in an upward direction to cause the said valveto rest against its seat 7.

The numeral 22 designates a second valve which is normally seated upon the lower end of the discharge spout 6 and this valve also has its upper face round or cone-shaped so that the carbid delivered thereon, in a manner presently to be described will be distributed to a carbid receiving pan 23 which is retained below the level of the water by suitable supporting rods 24-24 which are attached to the lower face 5 of the tank 4. The pan 23 preferably comprises a reticulated flat disk having a central opening which is surrounded by an upwardly extending annular sleeve 25, and the upper edge of the said sleeve supports a cone-shaped carbid directing member 26.

By reference to the drawings it will be seen that the valve 22 is of a materially greater size than that of the valve 12, so

that the carbid contacting with the rounded upper face of the said valve 22 will be properly spread when delivered to the water or to the pan 23.

The` valve 22 has its stem 27 passed `through the hollow stem 13 of the valve 12 and the said stem projects beyond the upper edge of the said hollow stem 13. The stem 2T also extends below the valve 22, the said extending portion being provided with a hook-sh aped member 28 which is engaged' by the hooked end 29 of a lever 30. This lever 30`has upper edge provided with spaced notches 31 which receive the eye or bail member 32 provided upon a weight 33, and the lever has, approximately centrally, connected thereto a flexible member in the nature of a chain 3st, the said chain being suspended from a suitable eye 35 that is attached to the cone-shaped lower portion 5 of the tank 11. It will be noted that the weight 33 is arranged opposite the side of the lining 2 adjacent which the weight 21 is disposed, but such arrangement is not absolutely essential, as the weight 21 is positioned a suitable distance above the weight 33.

The numeral 36 designates a perforated filtering member for the gas generated by the carbid after the same has been decomposed in the water in the apparatus, the said filter being, of course, disposed above the line of water and connected to a gas outlet pipe 37.

The numeral 38 designates the gas bell which is disposed in the water space between the casing 1 and its inner lining 2, the said bell, at its upper and lower portions being provided with guide wheels 39-39 whichcontact with the inner walls of the casing 1 and whereby the movement of the bell when buoyed by the generated gas will be materially assisted and also whereby the said bell will be properly spaced from the casing. rThe top of the bell, upon its inner surface, is centrally provided with an enlargement in the shapeof a flat disk 40, the said member 40 being disposed above the stems of both of the valves and being adapted, after the generated gas has flowed through the filter and outlet pipe, and the bell falls by gravity, to contact, first with the stem 27 of the valve 22, unseating the said valve 22, and when said stem has been moved to the level of the top of the hollow valve stem 13 of the valve 12, to move the said stem 13, simultaneously with a further movement of the stem 27 to unseat the valve 12. This, of course, permits of the carbid flowing through the opening 7 upon the round or cone-'shaped face of the valve 22 and distributed therefrom to the pan 23, as heretofore set forth. When a sufficient amount of carbid has been deposited upon the pan 23 to generate a suiiicient quantity of gas to elevate the bell 38, the weight 21, through the knuckle connection of the lever 17 with the hollow stem 13 of the valve 12 seats the valve 12. As the valve 22 cannot be seated until the stem thereof is entirely relieved of pressure from the bell, and as the stem thereof must necessarily travel a greater distance than the stem of the valve 12, the valve 22 will be seated at a time slightly later than the seating of the valve 12.

From the above description, taken in connection with the drawings, it will be noted that the valve 22 serves as a distributer for the carbid, that the pan 23 retains the carbid until the same is entirely decomposed, that the construction is simple, that the carbid inay be readily inserted in the tank 4l by elevating the bell thereabove, or, if desired, the top of the bell may be provided with a tightly closed opening 50 disposed above the opening S in the top of the tank 4, and that the merits of the improvement will be appreciated by those skilled in the art without further detailed description.

Having thus described the invention, what I claim is In an apparatus for producing acetylene gas, a casing having water therein, said casing having an inner lining spaced therefrom but connected therewith, said lining being provided with openings below the level of the water, a gas bell disposed between the inner lining and the casing, antifrictional guide wheels upon the bell and contacting with the casing, a carbid tank upon the open top of the inner lining, said tank having a lower funnel-shaped portion, the mouth of which providing a valve seat, a spout surrounding the seat, a perforated pan connected with the tank disposed below the level of the water, a sleeve connected to the top of the tank and projecting centrally therein, a cone-shaped guide upon the sleeve, a valve for the valve seat, said valve having a hollow stem projecting through the sleeve above the top of the tank, a` second and larger valve having an upper rounded face to engage with the lower edge of the spout, a stem for the valve extending through the hollow stem of the first named valve and projecting thereabove, weighted means for retaining the valve seated, and both of the valve stems adapted to be contacted by the bell when said bell is in its lowered position, and a gas outlet pipe for the casing.

In testimony whereof I atlix my si gnature in presence of two witnesses.
